Hall of Fame quarterback Dan Marino is among the latest group of NFL players to file a concussion-related lawsuit against the NFL.

Marino and 14 other former NFL players filed the lawsuit in a federal court in Pennsylvania May 28, joining more than 4,500 others who had previously accused the NFL of misleading players about the long-term dangers of concussions.

The NFL and the plaintiffs agreed on a $765 million settlement last August, but the settlement was rejected by a federal judge in January.

The suit filed by Marino and others is similar in nature to hundreds of earlier lawsuits, and accuses the NFL of "carelessness, negligence, intentional misconduct" regarding concussions, according to the documents filed last week and obtained by USA TODAY Sports.

The plaintiffs in the latest lawsuit are seeking money for medical treatment and compensation for long-term or chronic injuries. The 18-page filing does not include specific details about Marino's current health.

Marino, 52, retired in 1999 after playing 17 seasons for the Miami Dolphins. He did not have significant history of documented concussions, but dealt with a neck injury late in his career. He missed 11 games in 1993 after suffering a torn Achilles' tendon.

Marino spent the previous 12 years working as an analyst for CBS but parted ways with the network earlier this year. Marino has been in Buffalo visiting with fellow Hall of Fame quarterback and 1983 draftee Jim Kelly, who recently completed chemotherapy treatments. Marino participated in the Jim Kelly Celebrity Golf Classic on Monday.

Marino spoke with reporters in Buffalo before the Los Angeles Times was the first to report on the concussion lawsuit. Marino and his agent, Marvin Demoff, were not immediately available for comment.

Federal judge Anita B. Brody in January denied preliminary approval on the $765 million settlement, writing in her ruling that there wasn't enough analysis and information in the settlement to assure her that it could provide enough money to pay the claims of all the players deemed eligible.

The proposed settlement called for the formation of a $675 million fund to award money to players with a "qualifying diagnosis." She noted there are about 20,000 living former NFL players and the settlement would provide, for example, up to $3.5 million for a retired player with diagnosis of Parkinson's Disease and up to $5 million for one with a diagnosis of Lou Gehrig's Disease.

"Even if only 10 percent of retired NFL football players eventually receiving a qualifying diagnosis, it is difficult to see how the Monetary Award Fund would have the funds available over its lifespan to pay all claimants at these significant award levels," the judge wrote.

Other players who have filed concussion suits against the NFL include members of the Pro Football Hall of Fame such as Eric Dickerson, Tony Dorsett, Bob Little, Randy White and the estate of the late Lee Roy Selmon.
